Title: Improvements in or relating to Galvanic Batteries
IPC: H01M8/04276
Filed: 1967-09-12
Abstract: 1,177,168. Regulation of temperature and composition of a battery electrolyte supply. FINLAND, DEFENCE MINISTER OF. 12 Sept., 1967 [12 Sept., 1966], No. 41613/67. Heading H1B. [Also in Division G3] In a battery in which water and at least one other electrolyte component are fed into a mixer and thence as electrolyte through the cells of the battery, a first regulator controls the supply of the electrolyte components and hence the electrolyte composition so as to maintain a constant voltage output, a first duct supplies water directly from source to mixer and a second duct supplies water to the mixer via a heater, and a second regulator operated by a temperature sensor in the mixed electrolyte controls the proportions of water passing through the two ducts so as to maintain a preselected temperature in the mixed electrolyte. Preferably, a third regulator maintains the supply of water constant, despite variations in the voltage operating the supply pump. In Fig. 1 electrolyte is driven by pressure from vessel 3 from tank 1 to initiate the cell reactions; thereafter chromic acid and sulphuric acid are supplied from tanks 16 and 18 via pipes 17 and 19, and water from source 11 via pipes 12, 13, 14 and 15, by pumps P 2 , P 3  and P 1  respectively, to pipe 5 where they are mixed to form electrolyte, which is then passed through the two groups 6 and 9, joined by electrolyte duct 8, of cells having bipolar electrode plates 7 of zinc and carbon, and discharged through pipe 10; control 20 is a constant voltage regulator for pump P 1  to maintain constant water supply; pumps P 2  and P 3  are jointly regulated by control 21 responsive to the battery voltage; pipes 14 and 8 together form a countercurrent heat exchanger in which the water supply is heated by the electrolyte; a valve 22 adjusts the proportions of heated and unheated water entering the electrolyte and is operated by an electromagnet 23 actuated by control 24 which responds to the temperature, e.g. in pipe 5; water may continue to flow through pipe 14 to cool the electrolyte when valve 22 has closed this pipe, being discharged through an outlet simultaneously opened for this purpose.

IPC: D06B3/34
Filed: 1968-09-06
Abstract: 1,214,546. Feeding webs. SEMPERIT OSTERREICHISCH - AMERIKANISCHE GUMMIWERKE A.G. 6 Sept., 1968 [6 Sept., 1967], No. 42464/68. Heading B8R. A process for the continuous coating of a fabric strip comprises passing the strip, with its two ends sewn together, through a first strip storage device 2 then through a coating device 6 and then through a second strip storage device 1. The strip is passed more than once through the coating device. Before sewing the two ends together, the first portion of the strip is pulled through the storage devices and the coating device by a fabric band 5 and the end portions of the strip are then held stationary by first clamping rollers 11 disposed in front of the first storage device 2 and by second clamping rollers 10 disposed behind the second storage device 1. The leading edge of the strip is then detached from the pull-through band 5 and the two ends of the strip are then sewn together by a machine 7. During the time that the end portions are clamped by the rollers 10, 11 the coating device is fed from the first storage device 2 and the strip from the coating device accumulates in the second storage device 1. The endless strip is then passed through the coating device several times until the required thickness of coating is obtained. The clamping rollers 10, 11 are again used to enable the seam joining the ends to be undone and the leading edge of a new strip to be joined to the trailing edge of the old strip. The new strip is formed into an endless strip after its leading edge has been disconnected from the trailing edge of the old strip. Each storage device comprises a set of upper rollers 3 and a set of lower rollers 4 mounted on a sliding carrier 9 which can move up and down to vary the capacity of the device.

Title: Improvements in or relating to data recording apparatus
Inventor: RITZERFELD GERHARD
IPC: G06K1/00
Filed: 1967-09-19
Abstract: 1,185,204. Typewriters. G. RITZERFELD. 19 Sept., 1967 [21 Sept., 1966], No. 42660/67. Heading B6F. A punched or printed record of data printed on an original 19 by a typewriter or like machine 21 is produced on a record carrier by apparatus comprising a group of dies 81 operated in response to electrical impulses received from the typewriter keys, mechanism causing stepped relative motion between the dies 81 and the record carrier, and a line shift mechanism responsive to line shift mechanism or carriage traverse mechanism of the typewriter 21. The record carrier may comprise a cord 1, Fig. 1, divided into lines each comprising twenty character spaces 2 of four binary bits, the group consisting of four dies. Depression of a key 22 closes a switch 31 and causes an impulse to pass to a coder 32 and operate corresponding dies 81. The impulse also passes through a delay element 47 to actuate an electromagnet 85 which actuates an escapement mechanism driving the dies 81 one character space along the line in preparation for the next impression. A line shift on the typewriter causes a projection 53 associated with the platen roller thereof to close a switch 52 and produce an impulse actuating an electromagnet 56 which operates a line shift escapement mechanism. Key operation.-Coded impulses from the coder 32 pass through sliding contacts 73 to electromagnets 74 which lift links 77 to pivot levers 79 about a shaft 78 and depress the dies 81 against the action of springs 82. The dies 81 may perforate or print on the card 1. Character spacing escapement mechanism.- The electromagnet 85 includes an armature which pushes a stepping pawl 86 into engagement with a tooth on a rack 87 when the electromagnet is energized, thereby disengaging a locking pawl 88 from a second tooth on the rack, and enabling the rack, which carries the dies 81, to move along the line under the action of a spring 91 by an amount sufficient to prevent the locking pawl from re-engaging with the same tooth. When the electromagnet 85 is de-energized, springs 89, 90 return the pawls to the position shown such that the locking pawl 88 engages with a third tooth on the rack 87. Line spacing escapement mechanism.-An armature 57 of the electromagnet 56 operated by the line shift mechanism of the typewriter 21 coacts with a stepping pawl 58 and a locking pawl 60 which engage teeth on a ratchet 59 and enable a roller 92, carrying pins which engage with feed holes 4 in the card 1, to rotate incrementally under the action of a coil spring 61. A toothed wheel 67 engages teeth on the roller 92 and enables the coil spring 61 to be wound up. In an alternative embodiment (Figs. 1b 3, not shown), each line of the record carrier comprises eighty character spaces of ten bits arranged longitudinally of the carrier. Ten dies (118) are mounted on a stationary housing and character spacing is effected by incremental movement of a feed roller (122) carrying the record carrier, under the action of an escapement mechanism.
